What is the Total surface area of a Toblerone?
Form a net of the Toblerone and work out the area of each individual part of it and then add up the parts together to find its entire surface area
Does a pure sine wave exist in nature or is it man made only?
All electromagnetic radiation - including light in space, cosmic microwaves, stellar x-rays are pure sine waves. They existed billions of years before man appeared in the universe!
The sine of one of the acute angles in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
Elevation o Qattara Depression?
can someone help me get the answer to this question? The elevation of Qattara Depression is 133 metres below the sea level.
What are real life applications of the law of sines?
Land surveying makes an extensive use of the sine and cosine law. The idea is to subdivide the land into many triangles and to measure one side and two angels of each triangle. With the sine law the other two sides can be computed. The Mount Everest was found by this method to be the highest mountain on planet earth.
What are the importance of trigonometry?
Trigonometry is a type of math

Some Jobs like being a scientist or a mathematician include trigonometry
A periodic up-and-down motion.
What is the difference of trigonometry and geometry?
Trigonometry is a branch of geometry which is primarily concerned with the properties and measurement of triangles.
A sphere of radius 4000 miles has a circumference of 25132 miles. The distance between any two points on the surface of that sphere is simply 25132 times the angle between the two points divided by the angle of the full circle (360 degrees). If the two cities were ten degrees apart, the distance would be 698 miles. It does not matter if the two cities are on the same meridian or not - angular separation is the only thing that matters, except that the calculation of the angle in three-space is more complex than that in two-space.
What has opposite angles congruent?
Any polygon with an even number of sides (vertices) in which at least one pair of opposite angles are of the same measure.
What day of the week is 263 days from Monday?
The day of the week 263 days from Monday is Friday. Take 263. Divide by 7. You get 37.7something. Subtract 37, leaving the .7something. Multiply by 7. You get 4. Monday plus four days is Friday.
the sine rule, angle (a) and opposite length is eaqual to angle (b) and opposite length. which are also equal to angle (c) and opposite length. Sin A = Sin B = Sin C ------- -------- ---------- a -------- b -------- c
What is the correct notationfor the complex number 93 plus square root of-75?
It is 95 + 5*√3*i, the three multiplicands at the end can be put in other orders.
How do you learn trigonometry of class 11?
Attend the lectures in class 11 and pay attention. If you do not understand something ask.
How do you find the length of the hypotonuse of right angled triangles?
you can use pythagorean theorem formula:c² = a² + b²
you must have the values of the opposite side and adjacent side.
you may try below link for easy calculation
How many tangent lines could be draw on a straight line?
A tangent line is a line that is parallel to and intersecting a point on a curve, where the limit of the distance between two points on that curve (one of them being the point in question) and those two points also being on that line approaches zero.
Since a straight line has only one slope, at all points on the line, then there can only be one tangent line to a straight line, and the tangent line is the same line as the straight line.
What is a iscosilies triangLe?
First off, its isosceles.
An isosceles triangle is a triangle with two sides that have the same length. A triangle with 3 sides the same length is called equilateral, but it is also a form of an isosceles.
Note also that an isosceles will have two or more angles the same.
please answer this queand show the working out a large advertising ballon is tied to the roof of a 20 m high builing by a 50m rop which makes an angle of 42 degrees with the horizontal. find the height of the balloon above the ground correct to two decimal places?
Do points have a definite shape in geometry?
Technically they don't because the definition of a point is a specific place of a certain object in a graph, and you could keep cutting up the point infinity times and still not have the most exact location as possible. Thus, a point can be any shape, but for a point there will never be an exact location or a definite size or shape. Most points in geometry are little circles such as on a line graph, but a point could be a square. A point is just the most exact location of something in a geometry problem. That's all it is.
